1 Claim. 1

This invention relates to the art of water cooling and particularly spray nozzles or fluid distribution members adapted for attachment to conduits through which fluid is passing and from which a portion thereof is Withdrawn by the spray nozzle for conversion into minute particles.

One of the important objects of the instant invention is to provide a spray nozzle of the type designed to project laterally from pipes or the like, that comprises a number of separable sections held in operative position when the nozzle assembly is in its normal location.

A further aim of this invention is to provide a multi-part distribution nozzle of the aforementioned character, comprising a longitudinally split body having at least two sections, each of which cooperates to impart circular motion to the fluid entering the intake ports, one of which is created in each section of the body.

Heretoforc spray nozzles of the lateral type have been formed through the employment of numerous elements, each of which are separately cast, machined or otherwise manufactured. Such conventional nozzles are expensive to manufacture, may not be put into use immediately after casting or molding occurs, and in many instances, cannot be quickly remo-ved from the operative position for cleaning. This invention, therefore, provides a spray or distribution nozzle formed of plastic or other suitable moldable substance, the parts of which are identical, need not be machined after removal from the mold, and

are held together when the nozzle in its entirety is introduced into a threaded` opening formed in a uid conduit.

Minor objects of the invention including the specific form of each section of the nozzle body,r the manner of assembly for use, and the advantages arising from a unit embodying the invention, will appear during the course of the following specification, referring to the accompanying drawing, wherein:

Fig. l is a fragmentary sectional view through a length of conduit having a distribution nozzle embodying the invention mounted thereon.

Fig. 2 is a top plan view of the nozzle.

Fig. 3 is a side elevational View thereof.

Fig. 4 is a transverse cross sectional view taken on line IV-IV of Fig. 3; and

Fig. 5 is a longitudinal sectional view through the nozzle taken on the line of separation and looking in the direction oli the arrow.

Conduit I6 has a threaded opening I2 provided of a hole in the side thereof for the reception of at least one iluid distribution nozzle.

The nozzle per se comprises two sections I4 of like character, each of which has a smooth abutting face I6 provided with detents I8 to cooperate with a coacting part of the opposite section to preclude accidental lateral relative movement of sections I4 as the nozzle is' being manipulated prior to introduction into opening I2.

llwo of said sections I4 are employed to complete the nozzle body. The planar abutting faces lie on a plane intersecting the axis of the body and when the sections are together, the body has a polygonal head 20, a screw-threaded section 22 immediately below said head 20, an outlet orice 2.4 formed through the outer end wall on the axis of the body, and a pair of inlet ports 26. There is an inlet port 26 formed by each section I4. Each section is notched as shown in Fig. 5 to form three sides of the inlet port, the fourth side whereof is provided by the other section when the body is assembled.

Means for imparting circular motion to the fluid entering inlet ports 26, is in the nature of an inwardly curled lip 28 concentric to the axis of the nozzle body and extending the length of each inlet port 26. These lips 28 are substantially diametrically opposed as illustrated in Fig. 4, and such arrangement of parts together with the aring inner face of the hollow 39 of the body, insures that the fluid will be forced upwardly and out through orifice 24.

Each section I4 has a lip 28, an inlet port 26, a section of screw-threads 22, and a component part of outlet oriiice 24 formed thereby. These sections are easily molded, no machining is necessary prior to assembly, and installation, and removal of the nozzle body permits quick cleaning and relocating. These advantages as well as those emanating from simplicity, low cost of manufacture, and use of inexpensive material, will readily indicate that this multi-part distribution nozzle is advantageous and while the preferred form has been illustrated and described, it is desired to be limited only by the scope of the appended claim.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

A spray nozzle of the character described comprising a pair of cupped sections of substantially the same contour having their edges in abutting relation t0 form a hollow body; a notch formed in the side wall of each section adjacent to one end thereof to provide inlet ports, said notches tion along that edge thereof forming the first mentioned notches, said lips being eccentric to the axis of the body and directed toward each other to impart a whirling motion to the Water passing through the hollow body, said sections having cooperating detents formed on the abutting edges lto hold the threads of the two sections in operative relation.
